CORPORATION OF N EW YORK EXCAVATING BUCKET Application led October 2,1931. Serial No. 566,556.

rlhis invention relates to excavating devices and the improvements aredirected to novel means for detachably connecting one or more pneumatichammers or drills to an orange-peel bucket, or the like.

'l` hose skilled in the art to which this invention appertains are awarethat when an orange-peel bucket is being operated 1n a caisson or bin,the material therein 1s fre-I quently too solid tor the blades or scoopsot the bucket to penetrate and dislodge said material. Under theseconditions it is necessary to employ another tool, to break up thematerial so that the bucket can handle the same. lt the caisson be adeep one' it may be necessary to dismantle the bucket in order that oneof the operating lines may be employed to handle the hammer or drill;and possibly a man would have to be lowered into the caisson to handlethe hammer or drill.

The primary object of the present invention is to provide novel meanswhereby Yone or more pneumatic hammers or drills may be removablyattached to anvorange-peel bucket without dismantling the latter.V A

Another object resides in the provision of means tor securing a hammerto a bucket whereby said hammer may be held by the blades of the bowl ofsaid bucket, and whereby said hammer may be quickly attached or detached.without necessitating the removal of the bucket from the operatinglines.

Still another objectot' the invention is to provide an annulus adaptedto encircle the upper peripheral surface of the bowl of a bucket vtorthe support of aplurality of pneumatic hammers in concentric relation tosaid bucket.

A further object is to provide means for removably attaching saidannulus to said bowl of said bucket. i

A still further object ot the invention resides in the provision ofmeans, associated with said annulus, whereby said pneumatic hammers maybe maintained in a vertical position or may be adjusted individually toassume an inclined position to the right or the left of said verticalposition.

lith these objects in view, together with others which will appear asthe description proceeds, the invention resides in the novel formation,combination, and arrangement of parts, all as will be described morefully hereinafter, illustrated in the drawings, and particularly pointedout in the claims.

In said drawings:

Figure 1 is an elevation of'an orange-peel bucket with our inventionattached thereto, the bowl o said bucket being shown in central verticalsection. Y

Fig. 2 is an elevation of the lower portion of a bucket showing theannulus and the series of pneumatic hammers carried thereby.

Fig. 3 is a plan View ot said annulus and the hammers with the blades ofthe bucket in horizontal section to show the means for attachin g saidannulus to said blades.

Fig. 4l 1s a sectional detail, taken on the line 1 4 of Fig. 8,'to showone ot the hook closing ropes 10, all ot said parts being welllmown andcommon to buckets of the orangepeel type.

As previously pointed out it is proposed to arrange a single pneumatichammer centrally oit the bowl ot a bucket, and upon inspection of Fig. 1it will be noted that we have provided a post 1l having its upper endabutting the lower center ot the bucket, as indicated at 12, and beingmaintained in proper position by means of suitable securing devices 13.In this connection it will be observed that the blades of the bucket areopened and then closed so that the tips of said blades engage the lowerend of said post 11 thereby forming a four-point support for said post.As shown in Fig. 1, the lower end of said post projects slightly beyondthe points of thev bowl thus permitting the attachment'ot a pneumatichammer 14 to the projecting end of said post, suitable fastening means15 being employed for this purpose. Said hammer 14 is provided with theusual drill 16, and air hose 17, the latter extending up through thebowl and being 5 held in position by means of a clam 18 affixed to oneof the arms or links 8. he connection between the post and hammer can beso made that it merely means connecting the hammer to the lower end ofthe post and allowing the hammer to re-act against not only the post butthe combined weight of the bucket and the post. In view of the abovearrangement the hammer may be quickly attached or detached and themachine handling the bucket is able to handle and place 'the hammeranywhere within the range of the boom operating said bucket.

fIt is further proposed to provide means whereby a plurality ofpneumatic hammers zo may be arranged in concentric relation to the bowlof a bucket, and in the present embodiment of the invention, said meansincludes an annulus 19 adapted to encircle the bowl 5 and to besecurelyassociated therewith, as 26 will presently appear. Y

' f Upon inspection of Fig. 3 it will be noted that said annulus 19 isprovided with a series of radially projected lugs 20, each lug beingapertured as shown at 21, (Fig. 4),-for

M80 the receptionof ring-bolts 22, the upper ends of said bolts being.hooked, as indicatedat 23, to extend over the rim ofthe bowl and tocontact the inner upper peripheral surface thereof, as shown in Figs. 3and 4. The application of the nuts 24 obviously assures an intimateContact between said annulus and 4the blades 6 constituting the bowl 5.Revert- `ing to Fig. 3 it will be observed that said annulus 19 is alsoprovided with a series o`f projections 25 for supporting a plurality ofclamping members 26, each of said members comprising a pair of spacedapertured arms 27 adapted to be pivotally attached to said lpro`ections25 by means of bolts 28, as shown, 46 Sai clamping members 26 alsoincluding plates 29 whereby the pneumatic hammers 30 may be firmly heldin position. Air hose '.31 are provided for the hammers, said hose beingclamped to an adjacent link 8 by means of a clasp 32, or the like. Fromtheforegoing it is obvious that the bolts 28 may be manipurlated so thatthe series of hammers maybe `individually inclined to the right or leftof the vertical positions shown in Fig. 2, and in order to steady thehammers, each is provided with abrace 33, one end of the latter being Yadjustably connected to the upper part ofthe hammer and the other endbeing pivotally supported by clamp'34 attached to an ad- 00 jacent link8. In view of the plurality lof i apertures 35 in each of the braces 33,the hammers may be adjusted to swing through an are and assume aninclined position to the right or left of the vertical positions shown.

55 lWhile the body portion of the centralyhamybucket and held by theblades constituting mer 14 is positioned below the body portions of theouter hammers 30, it will be understood that drills of various lengthsmay be used so that the lower ends of all the drills will be positionedin the same horizontal plane. It will also be appreciated that theannulus 19 may be made to support any number of pneumatic hammers andthat the showimg of our hammers carried by said annuius is illumine andnet restrictive.

While lie present is a disclosure of the preferred embodiment of theinvention, it is to be Lm'derstood that the invention is not limitedthereto as various changes in the minor details of construction,proportion and arrangement `of parts may be resorted to withoutdeparting from the spirit of the invention .as defined in the appendedclaims.
